OBJECTIVE: To evaluate the efficacy of acupuncture in treating chronic fatigue syndrome (CFS) in Hong Kong. METHODS: A single-blinded, randomized controlled trial design was adopted. Participants meeting inclusion criteria were randomly assigned to a treatment and a control group according to 1:1 ratio, resulting in an effective sample size of 99, with 50 and 49 patients in treatment and control group respectively. The same set of acupuncture points, which were selected according to traditional Chinese medicine theories, was applied in both groups, while conventional needle acupuncture was applied in treatment group and sham acupuncture (without skin penetration) was applied in control group. Schedule of treatment was the same in both groups, i.e. twice a week for 4 weeks. Key outcome measures were Chalder's Fatigue Scale, diagnostic criteria for CFS of the US's Centre for Disease Control and SF-12 health-related quality of life (HQOL) questionnaire. Adverse events, if any, were recorded. RESULTS: Improvements in physical and mental fatigue and HQOL in both groups were observed, but the improvements in treatment group were significantly bigger than in control group (P<0.01 or P<0.05). No adverse events occurred. CONCLUSION: Acupuncture is a safe, effective treatment for CFS.

STUDY DESIGN: A retrospective review of patients who underwent 2-level anterior cervical discectomy and fusion (ACDF) with standalone polyetheretherketone (PEEK) cages for cervical spondylotic myelopathy (CSM). PURPOSE: To evaluate the efficacy of stand-alone PEEK cage in 2-level cervical interbody fusion for CSM. OVERVIEW OF LITERATURE: ACDF is a standard surgical procedure to treat degenerative disc disease. However, the use of additional anterior plating for 2-level ACDF remains controversial. METHODS: We reviewed outcomes of patients who underwent 2-level ACDF with stand-alone PEEK cages for CSM over a 7-year period (2007–2015) in a regional hospital. Japanese Orthopaedic Association (JOA) score, fusion rate, subsidence rate, cage migration, and cervical alignment by the C2–7 angle as well as the local segmental angle (LSA) of the cervical spine were assessed. RESULTS: In total, 31 patients (mean age, 59 years; range, 36–87 years) underwent 2-level ACDF with a cage-only construct procedure between 2007 and 2015. The minimum follow-up was 24 months; mean follow-up was 51 months. C3–5 fusion was performed in 45%, C4–6 fusion in 32%, and C5–7 fusion in 23%. Mean JOA score improved from 10.1±2.2 to 13.9±2.1 (p<0.01) at the 24-month follow-up. Fusion was achieved in all patients. Subsidence occurred in 22.5% of the cages but was not associated with differences in JOA scores, age, sex, or levels fused. Lordosis of the C2–7 angle and LSA increased after surgery, which were maintained for up to 1 year but subsequently disappeared after 2 years, yet the difference was not statistically significant. No cage migration was noted; two patients developed adjacent segment disease requiring posterior laminoplasty 3 years after ACDF. CONCLUSIONS: The use of a stand-alone PEEK cage in a 2-level cervical interbody fusion achieves satisfactory improvements in both clinical outcomes and fusion.

Purpose: This study was performed to evaluate the outcome of implementation of transanal total mesorectal excision (TaTME) for low rectal cancer in a regional hospital and in comparison to laparoscopic (Lap) TME. Methods: Consecutive patients with low rectal cancer of which the lowest border of the tumour was located beween 1 and 5 cm from the puborectalis who underwent TME at North District Hospital between January 2013 and December 2019 were included. Clinical, operative, and pathologic outcomes were compared between Lap TME and TaTME. The primary end point was complication profile. Results: Thirty-five patients underwent Lap TME and 45 patients underwent TaTME for low rectal cancer. The conversion rate of the TaTME group was significantly lower than that of the Lap TME group (4.4% vs. 20%, P=0.029), but the operating time was longer (259 minutes vs. 219 minutes, P=0.009). The tumour location was significantly lower in the TaTME group, but the distal resection margins were adequate and not different between both groups. The TaTME group had higher incidence rates of prolonged ileus and urinary tract infection, but the other complications were similar between the two groups. The resection margin positivity rates of the TaTME and Lap TME groups were 2.2% and 5.7%, respectively (P=0.670). At a median follow up of 39 months, no abnormal early recurrence was detected. Conclusion It is technically feasible and oncologically safe to perform TaTME in a medium-volume colorectal unit. Patients with difficult pelvic anatomy can benefit by reducing the risk of conversion and margin positivity rate.

OBJECTIVETo explore the personality-adjusting effect of electro-acupuncture treatment for depression and compared this treatment with paroxetine treatment.

METHODSA non-blinded, randomized controlled trial was adopted. Sixty depressed patients, who met trial criteria, were randomly assigned to the treatment and the control groups. In the treatment group, electro-acupuncture treatment was used, and paroxetine treatment was used in the control group. During the 24-week study period, 12 patients dropped out and 48 patients completed the study. The Minnesota Multiple Personality Inventory (MMPI) was adopted as the evaluation tool. At the same time, the Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS) and Montgomery-Asberg Depression Rating Scale (MADRS) were used to evaluate the psychological state. Evaluations were done before and after treatment.

RESULTSAfter treatment, patients' psychological state improved significantly in both groups (P<0.01). For the treatment group, within-group comparison between baseline and after 24 weeks of treatment showed that severity of depression had significantly decreased (P<0.01). MADRS and SDS scores decreased significantly (P<0.05) and MMPI subscale scores for hypochondriasis, depression, psychopathic deviate, psychasthenia, social introversion and fake decreased significantly (P<0.05). For the control group, severity of depression also decreased significantly. MADRS and SDS scores decreased significantly (P<0.05); and MMPI subscale scores for hypochondriasis, depression, hysteria, paranoia, and psychasthenia decreased significantly (P<0.05). Between-group comparison demonstrated that for the MMPI subscales paranoia and social introversion, the decrease of score was greater in the treatment group than in the control group (P<0.05). However, there were no other significant differences between the control group and the treatment group.

CONCLUSIONElectro-acupuncture is effective for treating depression and affects personality traits.
